The strips have a notch allowing their fastening together in the closed position. The notch has a first tongue (4) emerging form the base strip and a second tongue (5) emerging from the pivoting strip. Both tongues are placed back to back and head to toe for locking the strips when they are in the closed position. Both tongues are integral with the material constituting the strips and raised from this material. The second pivoting strip (6) is fastened to the base strip by a second pivot (7). This second pivoting strip and the base strip are provided with a fastening system enabling them to be fastened together in the closed position. A third tongue (8) on the base strip and a fourth tongue (9) on the second pivoting strip are placed back to back and head to toe to lock the strips in the closed position.

Description

L'invention est relative à un fermoir pour bracelet du type à boucle déployante comportant une lame de base sur laquelle est susceptible de se rabattre au moins une première lame pivotante, lesdites lames étant attachées ensemble par l'une de leurs extrémités au moyen d'une première articulation, ces lames comprenant un dispositif à cran leur permettant de s'accrocher l'une sur l'autre en position de fermeture.The invention relates to a clasp for a bracelet of the folding clasp type comprising a base blade on which is capable of being folded back at least one first pivoting blade, said blades being attached together by one of their ends by means of a first articulation, these blades comprising a notch device allowing them to hang on one another in the closed position.

Il est connu de maintenir fermé deux lames d'un fermoir à boucle déployante par un dispositif à cran. Le document CH-A-353 567 montre un fermoir comportant deux lames métalliques reliées par une charnière. L'une de ces lames présente une fente longitudinale et deux tenons et l'autre comporte une ouverture dans laquelle peuvent s'engager les tenons. De manière analogue, le document CH-A-671 499 décrit deux éléments d'un fermoir déployable, articulés l'un à l'autre. L'un des éléments comporte une pièce en matière plastique rapportée et déformable élastiquement. Cette pièce s'engage dans une ouverture rectangulaire ménagée dans l'autre élément, avec les bords de laquelle elle coopère en un engagement à friction ou à cran.It is known to keep two blades of a folding clasp closed by a notch device. Document CH-A-353 567 shows a clasp comprising two metal blades connected by a hinge. One of these blades has a longitudinal slot and two studs and the other has an opening in which the studs can engage. Similarly, the document CH-A-671 499 describes two elements of a deployable clasp, hinged to one another. One of the elements comprises an attached plastic part which is elastically deformable. This part engages in a rectangular opening made in the other element, with the edges of which it cooperates in a friction or notch engagement.

Dans tous ces exemples et dans tous les autres connus du déposant, il y a coopération entre une ouverture pratiquée dans une première lame et un élément élastique faisant partie d'une seconde lame. Ces dispositifs de retenue donnent satisfaction quand ils sont neufs, mais perdent de leur efficacité en vieillissant. On observe particulièrement une usure de l'ouverture. En effet cette dernière n'est pas élastique et s'use donc au lieu de fléchir ou de se déformer élastiquement. Il en résulte un manque de fiabilité et une insécurité à plus ou moins long terme quant à la fermeture du bracelet.In all of these examples and in all the others known to the applicant, there is cooperation between an opening made in a first blade and an elastic element forming part of a second blade. These retaining devices are satisfactory when they are new, but lose their effectiveness as they age. There is particularly wear on the opening. Indeed the latter is not elastic and therefore wears instead of bending or deforming elastically. This results in a lack of reliability and insecurity in the more or less long term as to the closure of the bracelet.

Pour pallier cet inconvénient, la présente invention propose de remplacer l'ouverture pratiquée dans l'une des lames par un second élément élastique coopérant avec le premier situé sur l'autre lame. Ainsi le dispositif à cran de l'invention est-il caractérisé par le fait qu'il comporte une première languette émergeant de la lame de base et une seconde languette émergeant de la première lame pivotante, lesdites première et seconde languettes se présentant dos à dos et en tête-bêche pour bloquer lesdites lames lorsqu'elles se trouvent en position de fermeture.To overcome this drawback, the present invention proposes replacing the opening made in one of the blades by a second elastic element cooperating with the first located on the other blade. Thus the notch device of the invention is characterized in that it comprises a first tongue emerging from the base blade and a second tongue emerging from the first pivoting blade, said first and second tongues being back to back and head to tail to block said blades when they are in the closed position.

L'invention sera comprise maintenant à la lecture de la description donnée ci-après à titre d'exemple et illustrée par le dessin dans lequel:

  • la figure 1 est une vue en perspective du fermoir de l'invention selon un premier mode d'exécution, le fermoir étant présenté en position ouverte,
  • la figure 2 est une vue en perspective du fermoir de la figure 1, ce fermoir étant présenté en position fermée,
  • la figure 3 est une vue en perspective du fermoir coupé selon la ligne III-III de la figure 2,
  • la figure 4 est une vue en perspective du fermoir de l'invention selon un second mode d'exécution, le fermoir étant présenté pour une partie en position ouverte et pour une autre partie en position fermée,
  • la figure 5 est une coupe longitudinale dans le fermoir de la figure 4, ce fermoir étant présenté en position fermée, et
  • la figure 6 est une coupe transversale dans une partie de la figure 4, cette partie étant montrée en position fermée.
The invention will now be understood on reading the description given below by way of example and illustrated by the drawing in which:
  • FIG. 1 is a perspective view of the clasp of the invention according to a first embodiment, the clasp being presented in the open position,
  • FIG. 2 is a perspective view of the clasp of FIG. 1, this clasp being presented in the closed position,
  • FIG. 3 is a perspective view of the clasp cut along line III-III of FIG. 2,
  • FIG. 4 is a perspective view of the clasp of the invention according to a second embodiment, the clasp being presented for a part in the open position and for another part in the closed position,
  • FIG. 5 is a longitudinal section in the clasp of FIG. 4, this clasp being presented in the closed position, and
  • Figure 6 is a cross section in part of Figure 4, this part being shown in the closed position.

Si l'on se réfère maintenant aux figures 1 à 3, le fermoir présente, selon le premier mode d'exécution, une lame de base 1 sur laquelle est susceptible de se rabattre au moins une première lame pivotante 2. Les lames 1 et 2 sont attachées ensemble par l'une de leurs extrémités au moyen d'une première articulation 3. Ces lames comprennent un dispositif à cran qui fait l'objet principal de la présente invention et qui leur permet de s'accrocher l'une sur l'autre en position de fermeture. Ce dispositif va être décrit maintenant en détail.Referring now to Figures 1 to 3, the clasp has, according to the first embodiment, a base blade 1 on which is likely to fall back at least one first pivoting blade 2. Blades 1 and 2 are attached together by one of their ends to the by means of a first articulation 3. These blades comprise a notch device which is the main object of the present invention and which allows them to hang on one another in the closed position. This device will now be described in detail.

Le dispositif à cran comporte une première languette 4 qui émerge de la lame de base 1 et une seconde languette 5 qui émerge de la première lame pivotante 2. Comme on le voit bien en figure 3, les première et seconde languettes 4 et 5 se présentent dos à dos et en tête-bêche quand le fermoir est bloqué en position de fermeture. On observe en effet, particulièrement en figure 3, que la tête de la languette 4 jouxte la racine de la languette 5 et que, de manière analogue, la tête de la languette 5 jouxte la racine de la languette 4, ces languettes s'appuyant l'une contre l'autre par leur dos respectif. Ainsi, dans le système à cran de l'invention, ce n'est pas seulement une languette qui s'accroche dans une ouverture, comme c'est le cas des fermoirs cités des documents antérieurs, mais deux languettes qui se crantent l'une sur l'autre. On multiplie ainsi par deux la force de retenue d'une lame sur l'autre. En effet, les languettes 3 et 4 présentant chacune un effet élastique, cet effet est doublé au moment où lesdites languettes sont appuyées dos à dos et en tête-bêche l'une contre l'autre, c'est-à-dire lorsque les lames sont en position de fermeture.The notch device comprises a first tongue 4 which emerges from the base blade 1 and a second tongue 5 which emerges from the first pivoting blade 2. As can be seen in FIG. 3, the first and second tongues 4 and 5 are presented back to back and back to back when the clasp is locked in the closed position. It is observed, in particular in FIG. 3, that the head of the tongue 4 adjoins the root of the tongue 5 and that, in a similar manner, the head of the tongue 5 adjoins the root of the tongue 4, these tongues being supported one against the other by their respective backs. Thus, in the notched system of the invention, it is not only a tongue which hooks into an opening, as is the case of the clasps cited in the prior documents, but two tongues which notch one on the other. This increases the retention force of one blade on the other by two. Indeed, the tongues 3 and 4 each having an elastic effect, this effect is doubled when said tongues are pressed back to back and back to back against each other, that is to say when the blades are in the closed position.

Les figures 1 à 3 montrent aussi que les languettes 4 et 5 sont munies chacune d'un biseau d'attaque référencé respectivement 20 et 21. Ces biseaux sont arrangés et dimensionnés pour permettre un glissement doux d'une languette sur l'autre au moment de la fermeture, ce qui assure d'abord un encliquetage progressif, puis un maximum de tension en position fermée des deux lames. On mentionnera également que les lames 1 et 2 peuvent être issues chacune et respectivement de profilés en bande qu'on coupe à la largeur voulue, ce qui évite de coûteux usinages. On observera aussi que les première et seconde languettes 4 et 5 peuvent être faites intégralement des matières constituant respectivement la lame de base 1 et la première lame pivotante 2, lesdites languettes étant levées desdites matières. On utilisera pour cela des méthodes de découpage et d'étampage.Figures 1 to 3 also show that the tongues 4 and 5 are each provided with an attack bevel referenced respectively 20 and 21. These bevels are arranged and dimensioned to allow a smooth sliding of a tongue on the other at the time of the closure, which first ensures a progressive snap-in, then a maximum tension in the closed position of the two blades. It will also be mentioned that the blades 1 and 2 can each come from, respectively, strip profiles which are cut to the desired width, which avoids costly machining. We will also observe that the first and second tongues 4 and 5 can be made entirely of materials respectively constituting the base blade 1 and the first pivoting blade 2, said tongues being lifted from said materials. Cutting and stamping methods will be used for this.

Dans le cas où le fermoir de l'invention ne possède qu'une seule lame pivotante 2 articulée sur la lame de base 1, un premier brin du bracelet (non représenté) serait attaché à des gonds 16 faisant parie de la première lame pivotante 2 et le second brin du bracelet (non représenté) serait attaché à d'autres gonds remplaçant l'articulation 7 située sur la lame de base 1. Ce mode simple n'est pas représenté aux figures, mais se trouve être très facilement imaginable.In the case where the clasp of the invention has only one pivoting blade 2 articulated on the base blade 1, a first strand of the bracelet (not shown) would be attached to hinges 16 forming part of the first pivoting blade 2 and the second strand of the bracelet (not shown) would be attached to other hinges replacing the articulation 7 located on the base blade 1. This simple mode is not shown in the figures, but happens to be very easily imaginable.

Comme le montrent les figures 1 à 3, le fermoir peut cependant présenter une seconde lame pivotante 6 attachée à la lame de base 1 par une seconde articulation 7. Dans ce cas le premier brin du bracelet (non représenté) est attaché aux gonds 16 faisant partie de la première lame pivotante 2 et le second brin du bracelet (également non représenté) est attaché à des gonds 17 faisant partie de la seconde lame pivotante 6. Dans le cas du fermoir présentant une lame de base 1 et deux lames pivotantes 2 et 6, deux solutions peuvent s'envisager pour bloquer la seconde lame pivotante 6 sur la lame de base 1:As shown in Figures 1 to 3, the clasp may however have a second pivoting blade 6 attached to the base blade 1 by a second hinge 7. In this case the first strand of the bracelet (not shown) is attached to the hinges 16 making part of the first pivoting blade 2 and the second strand of the bracelet (also not shown) is attached to hinges 17 forming part of the second pivoting blade 6. In the case of the clasp having a base blade 1 and two pivoting blades 2 and 6, two solutions can be envisaged to block the second pivoting blade 6 on the base blade 1:

La première solution est illustrée par les figures 1 à 3. Dans ces figures, le dispositif de fermeture accrochant la lame de base 1 sur la seconde lame pivotante 6 est identique à celui qui a été décrit ci-dessus. Une troisième languette 8 émerge de la lame de base 1 alors qu'une quatrième languette 9 émerge de la seconde lame pivotante 6. Ces troisième et quatrième languettes 8 et 9 se présentent dos à dos et en tête-bêche pour bloquer lesdites lames lorsqu'elles se trouvent en position de fermeture.The first solution is illustrated in FIGS. 1 to 3. In these figures, the closure device hooking the base blade 1 on the second pivoting blade 6 is identical to that which has been described above. A third tongue 8 emerges from the base blade 1 while a fourth tongue 9 emerges from the second pivoting blade 6. These third and fourth tongues 8 and 9 are back to back and head to tail to block said blades when they are in the closed position.

La seconde solution est illustrée par les figures 4 à 6. Comme on le voit sur ces figures, le dispositif de fermeture accrochant la lame de base 1 sur la seconde lame pivotante 6 comporte une ouverture 10 pratiquée dans la lame de base 1. De part et d'autre de ladite ouverture 10 et sous celle-ci, sont aménagés des logements 11 et 12. Faisant partie de la seconde lame pivotante 6 et comme cela est représenté aux figures 4 et 6, on trouve un système à poussoirs 13 actionnables manuellement. Ces poussoirs sont munis chacun de crochets 14 et 15 qui s'engagent dans les logements 12 et 11 respectivement, quand les lames 1 et 6 sont en position de fermeture. Ce système de fermeture à poussoirs et crochets est connu de l'état de la technique, aussi n'a-t-il pas été illustré et décrit dans plus de détail ici, mais seulement montré schématiquement. Le lecteur intéressé en trouvera une description complète dans le document CH-A-665 101. A noter que pour mieux montrer l'ouverture 10 et le logement 12 pratiqué sous ladite ouverture 10, la figure 5 ne montre pas le mécanisme à poussoirs.The second solution is illustrated in FIGS. 4 to 6. As can be seen in these figures, the device for closure hooking the base blade 1 on the second pivoting blade 6 has an opening 10 made in the base blade 1. On either side of said opening 10 and under it, housings 11 and 12 are arranged. part of the second pivoting blade 6 and as shown in FIGS. 4 and 6, there is a system of pushers 13 which can be actuated manually. These pushers are each provided with hooks 14 and 15 which engage in the housings 12 and 11 respectively, when the blades 1 and 6 are in the closed position. This closure system with pushers and hooks is known from the state of the art, so it has not been illustrated and described in more detail here, but only shown diagrammatically. The interested reader will find a complete description in document CH-A-665 101. Note that to better show the opening 10 and the housing 12 formed under said opening 10, FIG. 5 does not show the push-button mechanism.

Les figures 4 à 6 illustrent aussi un second mode d'exécution de l'invention. On voit en effet dans ces figures que la lame de base 1 comporte à la fois une troisième languette 8 qui émerge de ladite lame de base 1 et une ouverture 10 de part et d'autre et sous laquelle sont aménagés des logements 11 et 12. Grâce à cette disposition, la lame de base 1 peut recevoir au choix deux types de seconde lame pivotante 6.Figures 4 to 6 also illustrate a second embodiment of the invention. It can be seen in these figures that the base blade 1 has both a third tongue 8 which emerges from said base blade 1 and an opening 10 on either side and under which housings 11 and 12 are arranged. Thanks to this arrangement, the base blade 1 can optionally receive two types of second pivoting blade 6.

La seconde lame pivotante 6 du premier type est décrite à propos des figures 1 à 3 et comporte une quatrième languette 9 qui y émerge pour coopérer avec la troisième languette 8 de la lame de base 1, ces languettes se présentant dos à dos et en tête-bêche pour bloquer les lames 1 à 6 en position de fermeture.The second pivoting blade 6 of the first type is described with reference to FIGS. 1 to 3 and has a fourth tongue 9 which emerges therein to cooperate with the third tongue 8 of the base blade 1, these tongues being back to back and at the head - spade to lock the blades 1 to 6 in the closed position.

La second lame pivotante 6 du second type a été décrite et illustrée en figures 4 et 6. La seconde lame 6 comporte un système à poussoirs 13 actionnables manuellement, ces poussoirs étant munis de crochets 14 et 15 s'engageant dans les logements référencés respectivement 12 et 11 quand les lames 1 et 6 sont en position de fermeture.The second pivoting blade 6 of the second type has been described and illustrated in FIGS. 4 and 6. The second blade 6 comprises a system of pushers 13 which can be actuated manually, these pushers being provided with hooks 14 and 15 engaging in the housings referenced 12 and 11 respectively when the blades 1 and 6 are in the closed position.

En conclusion de ce qui précède la lame de base 1, exécutée selon les figures 4 à 6, est polyvalente en ce sens qu'on peut monter sur elle, soit une lame pivotante équipée d'une languette, soit une lame pivotante équipée de poussoirs actionnables manuellement.In conclusion of the foregoing, the basic blade 1, executed according to FIGS. 4 to 6, is versatile in the sense that it can be mounted on it, either a pivoting blade equipped with a tongue, or a pivoting blade equipped with pushers manually operable.
